UNITED STATES PATENT OFFICE- JOHN WARBURTON, OF PATERSON, NEW JERSEY, ASSIGNOR TO BENJAMIN EASTWOOD COMPANY, OF IPATERSON, NEW JERSEY.

WARPING-MACHINE.

To all whom it may concern:

Be it known that I, JOHN WARBURToN, a citizen of the United States, residing in Paterson, Passaic county, New Jersey, have invented certain new and useful Improvements in Warping-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to warping machines and it has reference particularly to means employed in such machines for effecting relative movement as between the reed or reeds thereof and the threads, whereby the latter will be prevented from wearing constantly at the same places on the reed dents and thereby producing nicks or cuts, reducing the efiiciency of the reed and making it likely to damage the threads.

In general, my objects are to construct a mechanism for effecting the relative move ment alluded to in such a manner as most efliciently to produce the desired result to retain the said mechanism as simple and inexpensive in construction as possible, and to make it capable of being applied to various warping machines without material alteration of the latter.

The invention consists in providing in suitable hearings in the carriage of the machine a rotary shaft which is driven upon the traversing movement of the carriage to actuate the means whereby the desired movement as between the reed or reeds and the threads is secured, the said shaft extending substantially at right angles to the path of movement of the carriage.

The invention further consists in certain combinations and arrangements of parts hereinafter pointed out in the clauses of the claim.

In the accompanying drawings, Figure 1 is a side elevation of a warping machine including the improved mechanism, the said Specification of Letters Patent.

machine being of that type in which the carriage is automatically traversed; Fig. 2 is a plan view, on a larger scale than Fig. 1, of a detail appearing in Fig. 1; Fig. 3 is a front elevation of the improved mechanism and of parts of the warping machine; Fig. 4 is a front elevation of a modification of the invention; Fig. 5 is a view like Fig. 1, but showing the improved mechanism modified to suit it to a warping machine whose carriage is shifted or traversed manually; Fig. 6 is a plan of a detail appearing in Fig. 5; Fig. 7 is a front elevation of another modification; Fig. 8 is a side elevation thereof; and, Fig. 9 is a sectional view on line wzv of Fig. 7.

a is the frame of the machine; 6 its carriage suitably guided therein so as to traverse laterally thereof; (Z the usual rotary traverse screw, rotated from the reel 6 by the sprocket and endless chain transmission f in the usual manner; and g a mechanism, coactive with the said screw and a rack h, for causing the traverse motion of the carriage on rotation of the screw. The carriage carries the usual rollers i for guiding the warp. It also carries the vertical guides for the small or condensing reed is, movable vertically therein. Forwardly from the carriage proper projects the usual arm 1 carrying at its extremity the upright m to which is secured, so as to be vertically adjustable, the bottom bar n of the frame 0 for the reed p; to the front face of upright m is secured a pair of vertical guides 9 receiving the tongues 1" of a bar 8 to which is hinged a frame t comprising a glass bar u arranged horizontally in proximity to the front face of reed p. The bar 8 and frame 6, carried thereby, are vertically reciprocated as follows: A forked bracket u is attached to the front of upright m, and in the extremities thereof is journaled a rotary shaft o carrying a bevel-pinion w and formed at its ends with the cranks 00. These cranks are connected with brackets y attached to bar 8 by the links a. A bracket 1 is attached to one side of the carriage and in this is journaled, at right angles to the path of movement of the carriage, the rotary shaft 2 carrylng at its forward end the bevel-pinion 3 meshing with the bevel-pinion w. At its rear end said shaft carries the toothed wheel 4 meshing with a rack 5 which extends parallel with the path of movement of the carriage and consists of a chain having hooks 6 at its ends, the shank of each hook being threaded and passed through a hook 7 which engages an outside flange 8 on the frame a, and carrying nuts 9 embracing the hook 7 between them and serving in adjusting the chain to the necessary tension. Thus as the carriage traverses to lay the sections of warp spirally on the reel, shaft 2 rotates in the carriage, and, transmitting rotary motion to shaft 1;, causes the frame If to reciprocate vertically; the warp extends over the bar a in this frame and therefore also moves vertically, so that the threads thereof are kept from wearing constantly at the same places on the dents of the reed 79. To accomplish the same effect with respect to reed 73, the latter is reciprocated from shaft 2 as follows: A cam 10 is fixed on shaft 2, being adapted to oscillate a lever 11 fulcrumed in a bracket 12 attached to the under side of the carriage; the part of the lever which actually bears against the cam is a set-screw 14 whose function will later appear. The levers inner end is forked, receiving in its fork 15 an inverted L-shaped reed-carrier 16, through which and the fork a pivot pin 17 is passed; the reed carrier 16 has its horizontal leg projecting under the center of the reed 7a, which is directly supported thereby, while its vertical leg is guided in a hole 18 in the carriage and receives a spiral spring 14 interposed between the lever and carriage. Thus when shaft 2 rotates reed 71: will be moved vertically with respect to the warp threads, preventing localized wear of the reed dents by the threads. The operating height of reed 73 may be altered by adjusting screw 14.

In Figs. 5 and 6 the mechanism so far described is substantially the same except that, no means being shown for accomplishing the automatic traverse of the carriage (it being intended to be moved by hand as occasion requires), the rack is moved longitudinally so as to impart rotary motion to the shaft whereby the relative movement as between the threads and the reeds is secured. 19 is an endless chain (affording the said rack) and extending around sprocket wheels 19 journaled in the brackets 20 fixed to frame a. The journal for one of these sprocket wheels is a shaft 21 (fixed therein) carrying a bevel-pinion 22 meshing with a bevel-pinion 23 fixed on a shaft 24 journaled in bracket 20 and carrying a sprocket-wheel 25 around which extends a chain 26 also extending around a sprocket-wheel 27 carried by the reel snart 2&5. W hen the reel rotates, rotary motion will be transmitted to shaft 2, as will be obvious, accomplishing the relative movement as between the reeds and the warp threads the same as already described.

The mechanism shown in Fig. 4 is substantially the same as that shown in Figs. 1, 2, 5 and 6 except that the means for trans mitting motion from shaft 2 to the frame t is different. In a bracket 29 attached to the upright m is journaled a shaft 30 which is parallel with shaft 2, which may also be journaled at its forward end in said bracket. This shaft (30) and shaft 2 carry sprocket wheels 31 around which extends an endless chain 32, whereby rotary motion of shaft 2 is transmitted to shaft 30. Each shaft carries a crank 33 which is pivotally connected with bar 8 by a link 34, the cranks being relatively so disposed that (the sprocket wheels being of equal diameter) bar 8' is kept constantly horizontal in its reciprocations. Upon relative movement as between the carriage and the rack from which the shaft derives its rotary motion being effected a rise and fall movement will be imparted to the glass bar a, as will be manifest.

In Figs. 7, 8 and 9, bar 8, instead of being guided at its ends, carries the depending closely disposed and parallel rods 35 held in the clips 36 on bar 8; these rods are guided in the upper and lower brackets 37 secured respectively to the bar a of the reed frame 0 and to the upright m. The shaft 2 may be journaled in an arm 38 depending from lower bracket 37, and it carries a crank 39; at the other end of said bracket is pivoted a lever 40 whose free end is connected with the crank 39 by a link 41. At a point halfway between the fulcrum of the lever and the point where link 41 is pivotally connected with it a screw 42 is tapped into the lever, serving as the pivot for a link or pitman 43 pivoted at a central point of bar 8. The mode of operation of this arrangement will be obvious. By providing means for guiding bar 8 and the parts it supports which are disposed close to its vertical center or axis and transmitting the motion to it by a lever (such as 40) having its fulcrum and the pivoting points for the links 41 and 43 disposed as described, the desired motion is accomplished wit-h the minimum of friction and binding and in such manner as to be most perfectly uniform.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent is:

The combination with the carriage of a warping machine, said carriage having vertical guiding means, of a reed member and a warp engaging member arranged in said carriage and one being movable vertically in the guiding means, a lever fulcrumed in the carriage in a plane parallel With the path of In testimony, that I claim the foregoing, travel of the carriage, means for transmit- I have hereunto set my hand this 14th day ting motion from the lever to said movable of April, 1910. member, and means for vibrating the lever 0 comprising a rotary part journaled in the carriage on an axis extending transversely Witnesses: of the path of travel of the carriage, sub- JOHN WV.
